Good day, Out of not wanting to go up stairs to turn down the thermostat all the time I want to get in to home automation. My problem is where the thermostat is located I only have 5" between the molding around 2 doors (one to a room, the other to the HVAC unit itself). I'm having no luck finding a z-wave thermostat that with fit in the space I have to work with, so I was hoping someone hear could make a suggestion. I have not purchased anything yet, so if something not-z-wave would fit, please let me know what controller I could use as well.

My suggestion is manipulate the space. A good finish carpenter with a good selection of router bits can cut into the molding of each vertical piece and refinish the cut out to look intentional. It's pretty common in older homes when switches were added after construction.

Alternatively, could a z-wave thermostat be mounted inside the HVAC closet? If your orbiter controls it there is no real reason to get to its display. In my home the 2gig thermostat is fairly hidden behind a door that is almost always left open and in the main hallway where the old thermostat was mounted is a cradled WebDT.

I set that orbiter to "Hallway" as a room, and created over a dozen scenes that only appear when in room 'hallway.'

Thanks for the help. I've found model TZ43 that is 5”x3”x3/4” from Residential Control Systems Inc, and ordered one online for $175 US. If it does not fit or I don't like the look I'll try a 2-piece unit instead.

As for looks, the Honeywell WiFi Smart Thermostat RTH9580WF looks perfect from a size and form factor, but I don't see API info on their WiFi protocol to see if it would have the same issues as the nest.

Thanks again,

Edit: In case anyone comes across this thread. The Manufacturer web site said 5x3x3/4, but the specs in the product sheet are 6x4x3/4, and actual size is 5-3/4 x 3-15/16 x 1/2. I contacted RCS to ask them to correct it. It does overlap, but it does not look bad. I' gonna keep it.

From what I've seen around the net, the Honeywell has a proprietary protocol, and may require you to create an account for the more advanced features on the Tstat. At least, you have to create an account to use the mobile apps. http://wifithermostat.com/Products/WiFiSmartThermostat/

I recently bought the Radio Thermostat CT-80, which is less pretty than the Honeywell, but more capable with an open API (IMHO). It's bigger than the 5" you were looking for.
